2003 CHEVROLET EXPRESS key

Changes or modications to this system by other than
an authorized service facility could void authorization to
use this equipment.
At times you may notice a decrease in range. This is
normal for any remote keyless entry system. If the
transmitter does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:
Check the distance. You may be too far from your
vehicle. You may need to stand closer during
rainy or snowy weather.
Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the
left or right, hold the transmitter higher, and
try again.
Check to determine if battery replacement or
resynchronization is necessary. See “Battery
Replacement” and “Resynchronization” under
Remote Keyless Entry System Operation on
page 2-4.
If you are still having trouble, see your dealer or a
qualied technician for service.

Matching Transmitter(s) to Your
Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your vehicle.
If a transmitter is lost or stolen, a replacement can
be purchased through your dealer. Remember to bring
any remaining transmitters with you when you go to
your dealer. When the dealer matches the replacementtransmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock
your vehicle. Each vehicle can have a maximum of
four transmitters matched to it.
Resynchronization
Resynchronization may be necessary due to the
security method used by this system. The transmitter
does not send the same signal twice to the receiver. The
receiver will not respond to a signal that has been
sent previously. This prevents anyone from recording
and playing back the signal from the transmitter.
To resynchronize your transmitter, stand close to your
vehicle and press and hold the lock and unlock
buttons on the transmitter at the same time for
seven seconds. The door locks should cycle to conrm
synchronization. If the locks do not cycle, see your
dealer for service.

Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about four years.
You can tell the battery is weak if the transmitter won’t
work at the normal range in any location. If you
have to get close to your vehicle before the transmitter
works, it’s probably time to change the battery.
Notice:When replacing the battery, use care not to
touch any of the circuitry. Static from your body
transferred to these surfaces may damage the
transmitter.To replace the battery in the keyless entry transmitter,
do the following:
1. Use an object like a coin to pry open the transmitter.
2. Once the transmitter is separated, use an object
like a pencil to remove the old battery. Do not use
a metal object.
3. Remove and replace the battery, positive (+)
side down.
4. Snap the transmitter back together tightly to be sure
no moisture can enter.
5. Press and hold the lock and unlock buttons on the
remote keyless entry transmitter for seven seconds
to resynchronize the transmitter.
6. Check the operation of the transmitter.

Doors and Locks
Door Locks
{CAUTION:
Unlocked doors can be dangerous.
Passengers — especially children — can
easily open the doors and fall out of a
moving vehicle. When a door is locked, the
handle will not open it. You increase the
chance of being thrown out of the vehicle
in a crash if the doors are not locked. So,
wear safety belts properly and lock the
doors whenever you drive.
Young children who get into unlocked
vehicles may be unable to get out. A child
can be overcome by extreme heat and can
suffer permanent injuries or even death
from heat stroke. Always lock your vehicle
whenever you leave it.
Outsiders can easily enter through an
unlocked door when you slow down or
stop your vehicle. Locking your doors can
help prevent this from happening.There are several ways to lock and unlock your vehicle.
If your vehicle is equipped with keyless entry, see
Remote Keyless Entry System on page 2-3for more
information.
From the outside, use your key.
To lock the door from the
inside, slide the manual
lever on your door down.
To unlock the door, slide
the manual lever up.

Theft-Deterrent Systems
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal.
Passlock®
Your vehicle is equipped with the Passlock®
theft-deterrent system.
Passlock®is a passive theft-deterrent system. Passlock®
enables fuel if the ignition lock cylinder is turned with
a valid key. If a correct key is not used or the ignition
lock cylinder is tampered with, fuel is disabled.
During normal operation, the SECURITY light will go off
approximately ve seconds after the key is turned to
RUN. SeeSecurity Light on page 3-36.
If the engine stalls and the SECURITY light ashes,
wait until the light stops ashing before trying to restart
the engine. Remember to release the key from
START as soon as the engine starts.
If the engine is running and the SECURITY light comes
on, you will be able to restart the engine if you turn the
engine off. However, your Passlock
®system is not
working properly and must be serviced by your dealer.
Your vehicle is not protected by Passlock
®at this time.
You may also want to check the fuse. SeeFuses
and Circuit Breakers on page 5-92. See your dealer
for service.
Starting and Operating Your
Vehicle
New Vehicle Break-In
Notice:Your vehicle does not need an elaborate
break-in. But it will perform better in the long run if
you follow these guidelines:
Keep your speed at 55 mph (88 km/h) or less for
the rst 500 miles (805 km).
Do not drive at any one speed — fast or
slow — for the rst 500 miles (805 km). Do not
make full-throttle starts.
Avoid making hard stops for the rst 200 miles
(322 km) or so. During this time your new brake
linings are not yet broken in. Hard stops with new
linings can mean premature wear and earlier
replacement. Follow this breaking-in guideline
every time you get new brake linings.
Do not tow a trailer during break-in. SeeTowing a
Trailer on page 4-34for more information.

Ignition Positions
Use the key to turn the ignition switch to four different
positions.
A (Lock):This position locks the ignition and
transmission. It is a theft-deterrent feature. You will only
be able to remove the key when the ignition is turned
to LOCK.Notice:Using a tool to force the key from the
ignition switch could cause damage or break the
key. Use the correct key and turn the key only with
your hand. Make sure the key is in all the way. If
none of this works, then your vehicle needs service.
B (Accessory):This position lets you use things like
the radio and the windshield wipers when the engine
is off.
Notice:Lengthy operation of features such as the
radio in the accessory ignition position may
drain the battery and prevent your vehicle from
starting. Do not operate your vehicle in the
accessory ignition position for a long period
of time.
C (Run):This is the position for driving.
D (Start):This position starts the engine.
Retained Accessory Power (RAP)
The Retained Accessory Power (RAP) feature will allow
certain features on your vehicle to continue to work
for up to 10 minutes after the ignition key is turned to
